Title: Improvements in or relating to gyroscopic compasses
IPC: G01C19/38
Filed: 1937-12-18
Abstract: 507,643. Gyroscopic apparatus. BROWN, S. G. Dec. 18, 1937, Nos. 35071/37 and 2996/38. [Class 97 (iii)] In order to prevent errors due to rolling and/or pitching of the supporting craft counteracting forces or movements are applied to a pendulous element, which modifies or controls the directive properties of a gyroscope, from a source located apart from the pendulous element. The Figure shows the application of the invention to a gyro compass of the'type described in Specifications 22379/14, 124,529, and 124,533, [all in Class 97 (iii)]. The gyroscope (not shown) is carried by a pendulous frame 1 pivoted on an athwartship axis 3-3 in a ring 2 pivoting in turn about a fore-and-aft axis 4-4, The frame 1 constitutes the pendulous element. The correcting couples are applied about the axes 3, 4 by torque motors 7, 6 respectively. The torque motor 6 is excited by a generator 8 driven by a motor 9, the field winding 13 of which is connected between the mid-point 14 of a battery and the positive or negative terminal according to the setting of a two-way switch 15. The contact arm of the switch 15 is carried by a gyroscope 16 arranged to precess about a vertical axis 18 when the supporting craft rolls. Precession of the gyroscope 16 is restrained by springs 20, 21, carried by a nut 23 on a screwed spindle 24 driven by the motor 9 which is thus operated in accordance with the magnitude and direction of the roll. The torque motor 7 may be similarly excited in accordance with the magnitude and direction of pitching by a generator 31 and motor 30 controlled by a gyroscope 26 responding to rate of pitching. In a modification in which the gimbal system of the pendulous frame I is rotated by a compass repeater, the correcting torques may be applied about one axis only since the pendulous deflections about the other axis do not produce undesired precession of the gyro. Switches may be provided to render the correction mechanism inoperative. When the pendulous element comprises intercommunicating liquid vessels the correcting force may be supplied by moving either or both the vessels or by displacing a weight thereon.

Filed: 1938-12-03
Abstract: 514,142. Ball joints. FREED, K. B. Dec. 3, 1938, No. 35319. [Class 65 (ii)] A mounting for a pendulum arm 5 comprises a resilient member 12 having the form of a body of revolution, preferably that of a ball, held between rigid members 1 and 2, which are so adjustable relative to each other that the resilient member forms a pad-like enlargement 14 between them. This enlargement forms a supporting bearing edge between the resilient and rigid members and restrict the freedom of movement of the arm 5. In a modification the resilient member 12 comprises a core of rigid material such as wood covered with a layer of rubber material. The cap 3 which prevents the resilient material of the member 12 creeping through the opening 8 of the adjustable ring 2 may be dispensed with if desired. The pendulum arm 5 may be rigidly connected to the member 12 by a bolt 11 as shown, or may be connected to the cap 3 only.

Abstract: 1,121,435. Packaging molten materials. ESSO RESEARCH & ENG. CO. 8 Aug., 1966 [20 Aug., 1965], No. 35858/65. Heading B8C. A method of packaging a solid or semi-solid material, e.g. asphalt, consists in heat-liquefying it and delivering it to a container which is substantially immersed in a cooling bath, cooling means also being applied to the container at a position above the cooling liquid level. As described, the container consists of a preferably continuous sheath from which packages are formed after filling by transverse pressing and cutting. The sheath is preferably of plastics material, and can be formed either by joining the edges or directly by extrusion blowing. The filled packages sink in the bath after severance, and are gathered by a conveyer. Preferably the cooling liquid is chosen to have a density intermediate those of the material in liquid and substantially solid states respectively. The cooling of the package above the cooling liquid level can be effected by water spray or air jet.

Abstract: 1455242 Road vehicle signalling apparatus BONNELLA SWITCHES Ltd 5 Nov 1973 [4 Aug 1972 6 Dec 1972 21 Dec 1972] 36437/72 56230/72 and 59078/72 Heading G4Q [Also in Division H1] Relates to a direction-indicator switch assembly of the type comprising a manually operable rotor mounted in a body for movement from a neutral to first and second operative positions of opposite senses, switch contacts closed when the rotor is in either operative position, an indexing mechanism arranged to retain the rotor in either operative position, and a cancelling mechanism operated by a cancelling member moving as the steering wheel is moved to its central position to return the rotor towards its neutral position. According to the invention the cancelling mechanism comprises a pair of rotatable devices which are independent of the indexing mechanism and which are arranged to be engaged by the rotor on its movement to an operative position to bring at least one of the pair into the path of travel of the cancelling member, the rotor carries a pair of resilient arms each arranged to engage the corresponding rotatable device when the rotor is turned to an operative position to cause the respective rotatable device to be brought into the above path of travel. In the embodiment rotor 20 is of nylon with integral arcuate arms 25 each terminating in a ball 25A; turning of manually operable arm 26 rotates the rotor by a lever 27 engaging the sides of a slot 29. Nylon cranks 31 are spring-biased and are moved by the appropriate balls. The indexing mechanism consists of plungers 40A, 40B carried by the rotor and spring-loaded and co-operating with the faces of nylon cam inserts 41A, 41B, see also Figs. 6, 7 (neither shown), located in openings in a cover-plate 14. For self-cancelling after executing a turn arm 34 of crank 31 is pushed by a lug 38 and the rotor is driven to its neutral position by member 40A being brought out of an appropriate recess (42, 44, Fig. 6). Switch contacts 70 for head-lamp energization are actuated by a slider 60, Fig. 3, indexing being effected by a spring-biased plunger 61. When that plunger is in recess 64 high-beam illumination is afforded and when in recess 63 dipped-beam illumination ensues. Fixed contacts (73, Fig. 8, not shown) are carried by a resin (e.g. melamine) insert (72) secured in base 12; silver inlays are utilized for some of them. Contacts in a handle at the free end of arm 26 are closed when the arm is moved inwardly for energizing a horn. The contacts for the directionindicators are not particularly described.

The polymerization may take place in a mixture of methanol and water. The product may be cured using a difunctional epoxide curing agent, ethylene amino stearinated substituted methane or tris-2-methylaziridino-phosphine oxide.
